mmotm git tree since-4.6 branch created (was: mmotm 2016-05-23-16-51 uploaded)
From: Michal Hocko
Date: Tue May 24 2016 - 05:56:39 EST
I have just created since-4.6 branch in mm git tree
(http://git.kernel.org/?p=linux/kernel/git/mhocko/mm.git;a=summary). It
is based on v4.6 tag in Linus tree and mmotm-2016-05-23-16-51.
As usual mmotm trees are tagged with signed tag
(finger print BB43 1E25 7FB8 660F F2F1 D22D 48E2 09A2 B310 E347)
